Notes: This genus is only known from the type collection, which was pathogenic on living leaves of Orites lancifolius (morphology see Inácio and Cannon 2008; Wijayawardene et al. 2018, 2020). Thallomyces is characterized by superficial, dark brown to black, coriaceous, flat ascomata forming on branching, brown hyphae, which produce round to irregular, brown to dark brown appressoria (Inácio and Cannon 2008).
